Going to El Salvador with my family but I have many tattoos..

There is always a risk but you can minimize it a lot by the way you dress and carry yourself.

Be polite and respectful to cops and the military there and you should be fine.

Remember there are no civil or human rights in El Salvador right now, so if a soldier approaches you and asks you to take off your shirt, you do it without question. Doesn't matter if you are not doing anything suspicious or if they have a warrant or not. Be prepared to listen and follow their orders without question and show your ID.

Soldiers and cops. They both have authority to arrest civilians.

Crazy huh?
